I disagree. I've heard Bill Gates speak and spoken with profs who worked with him; he is deeply informed on the health and edu issues he works on. If we can get smart, creative people tackling those, all the better. Some problems don't have a market solution.
Gates might be the exception, and I do admire his work on malaria. But I really do wonder if there isn't a bigger idea that he's cowering away from in his quest to simply give his fortune away.
The quest to give his fortune away and cowering from a bigger idea?
He is changing the way development works. He is better funded than almost anyone else with no obligation to any other stakeholders (namely governments and political entities that use aid as a political chip).
He gets the opportunity to, as a private individual, challenge the market failures of our time. Who else is going to fund research aimed at saving the world's poorest with little chance of ROI? He can basically act like China does with their foreign aid but without taking all their natural resources in exchange.
If you truly think there is some big idea he is cowering from, you may have the greatest imagination I know of.
It doesn't read like a quest to give his fortune away, it looks more like a quest to try and solve some of the most intractable problems of poverty that the world faces. His legacy is trying to make the world a better place for the people sitting at the very bottom who capitalism has forsaken.
I don't dispute that his work has helped many, many people. I also acknowledge that simply putting money toward some of those dire problems now will ease a great deal of suffering, which is wonderful.
But philanthropy is an old fashioned way to solve problems. I guess I have this hope that someone like Gates would see a solution that took a very unexpected path.
